This change enables preloading string arguments for USDT hooks. A previous commit enabled this on the bpf side. This commit adds the required logic for the user space side. As USDT hooks apply to user space programs, some of the program's memory may not be paged in when the hook fires. Adding this sleep-able program allows us to handle this scenario by triggering page faults as required to facilitate argument reading. Signed-off-by: Andy Strohman astrohma@isovalent.com
